Description

Technical Field

[0001] The utility model relates to the technical field of saw blade structures, in particular to a saw blade with multi-peak teeth. Background Art

[0002] A saw blade can cut metal parts, and its shape is circular. The structure of a certain saw blade is as Figures 1 to 3 shown. It includes a saw blade body 1. Along the circumferential direction of the outer edge of the saw blade body 1, a plurality of tooth seats 2 are fixedly arranged. Each tooth seat 2 is integrally formed with the saw blade body 1. A cutter head 3 is welded on the tooth surface of each tooth seat 2. A bevel 4 is opened between the top surface of the cutter head 3 and its front end face, and between the top surface of the cutter head 3 and its rear end face. The intersection of the bevel 4 and the top surface of the cutter head 3 forms a tool tip 5, and the intersection of the bevel 4 and the left end face of the cutter head 3 forms a side cutting edge 6.

[0003] The method of using this saw blade to cut metal parts is as follows:

[0004] Sa. Workers fixedly install the saw blade body 1 on the main shaft of the cutting equipment, and then fix the metal part tooling to be cut.

[0005] Sb. Workers turn on the cutting equipment. The cutting equipment drives the main shaft to rotate. The main shaft drives the saw blade body 1 to rotate. The saw blade body 1 drives each cutter head 3 thereon to move synchronously. Then, the cutting equipment controls the rotating saw blade to move towards the metal part. Among them, the two tool tips 5 of the first cutter head 3 first cut an opening 8 on the metal part 7, as Figure 4 shown. Then, the two side cutting edges 6 of the second cutter head 3 respectively cut the materials on both sides of the opening 8 to widen the width of the opening 8.

[0006] Sc. In this way, by alternately cutting the metal part with each cutter head 3 on the saw blade, the metal part 7 can be cut off.

[0007] However, although this saw blade can cut metal parts, there are still the following technical defects in terms of technology:

[0008] I. In step Sb, when the cutter head 3 cuts an opening 8 on the metal part 7, the amount of material cut off at one time is large, and the corresponding cutting force generated is large. There are only two tool tips 5 on the cutter head 3 to share this cutting force, resulting in the two tool tips 5 being damaged in a short time and unable to continue participating in cutting. As a result, the entire saw blade can only be scrapped, and there is a technical defect of short service life.

[0009] II. In step Sb, when the two side cutting edges 6 of the cutter head 3 cut the materials on both sides of the opening 8 respectively, the side cutting edges 6 are still subject to the resistance of the materials, resulting in the inability of the side cutting edges 6 to smoothly cut the materials on both sides of the opening 8. As a result, after the metal part 7 is cut off, burrs are formed on both sides of the fracture (while technically required, there should be no burrs on both sides of the fracture after the metal part 7 is cut off). Therefore, this kind of saw blade has a problem with cutting quality.

[0010] Therefore, there is an urgent need for a saw blade with multi-peak teeth that has a long service life and can improve the cutting quality of metal parts. Utility Model Content

[0011] The purpose of the present utility model is to overcome the shortcomings of the prior art and provide a saw blade with multi-peak teeth that has a long service life and can improve the cutting quality of metal parts.

[0012] The purpose of the present utility model is achieved through the following technical solutions: A saw blade with multi-peak teeth, which includes a saw blade body. Along the circumferential direction of the outer edge of the saw blade body, a plurality of tooth seats are fixedly arranged. A multi-peak tooth A is welded on the inner end surface of the tooth seats arranged at intervals. An arc-shaped groove is formed on the top surface of the multi-peak tooth A. The intersection of the two side walls of the arc-shaped groove and the top surface of the multi-peak tooth A is the first cutting edge tip. Between the top surface of the multi-peak tooth A and its front end surface, and between the top surface of the multi-peak tooth A and its rear end surface, stepped surfaces A are respectively formed. The intersection of the stepped surface A and the top surface of the multi-peak tooth A constitutes the first cutting edge tip. The intersection of the stepped surface A and the left end surface of the multi-peak tooth A constitutes a stepped cutting edge A. A plurality of second cutting edge tips intersecting with the stepped cutting edge A are arranged on the stepped surface A;

[0013] Between every two adjacent multi-peak teeth A, a multi-peak tooth B welded on the inner end surface of the tooth seat is arranged. The intersection of the top surface of the multi-peak tooth B and its left end surface constitutes a straight cutting edge. Between the top surface of the multi-peak tooth B and its front end surface, and between the top surface of the multi-peak tooth B and its rear end surface, stepped surfaces B are respectively formed. The intersection of the stepped surface B and the left end surface of the multi-peak tooth B constitutes a stepped cutting edge B. A plurality of third cutting edge tips intersecting with the stepped cutting edge B are arranged on the stepped surface B.

[0014] A central mounting groove is formed in the middle of the saw blade body.

[0015] The distance between every two adjacent multi-peak teeth A on the saw blade body is equal, and the distance between every two adjacent multi-peak teeth B on the saw blade body is equal.

[0016] Both the multi-peak tooth A and the multi-peak tooth B are carbide teeth.

[0017] The four first cutting edge tips on the multi-peak tooth A are in the same plane.

[0018] The utility model has the following advantages: long service life and improved cutting quality of metal parts. Description of the Drawings

[0034] The following further describes the present utility model in conjunction with the accompanying drawings. The protection scope of the present utility model is not limited to the following:

[0035] As Figures 5 to 10 shown, a saw blade with multi-peak teeth includes a saw blade body 1. A central mounting groove 18 is provided in the middle of the saw blade body 1. A plurality of tooth seats 2 are fixedly arranged on the outer edge of the saw blade body 1 along its circumferential direction. A multi-peak tooth A9 is welded on the inner end surface of the tooth seats 2 arranged at intervals. An arc groove 10 is provided on the top surface of the multi-peak tooth A9. The intersection of the two side walls of the arc groove 10 and the top surface of the multi-peak tooth A9 is the first cutting edge 11. A stepped surface A is provided between the top surface of the multi-peak tooth A9 and its front end surface, and between the top surface of the multi-peak tooth A9 and its rear end surface. The intersection of the stepped surface A and the top surface of the multi-peak tooth A9 forms the first cutting edge 11. The intersection of the stepped surface A and the left end surface of the multi-peak tooth A9 forms a stepped cutting edge A12. A plurality of second cutting edges 13 intersecting with the stepped cutting edge A12 are provided on the stepped surface A; the four first cutting edges 11 on the multi-peak tooth A9 are in the same plane.

[0036] A multi-peak tooth B14 welded on the inner end surface of the tooth seat 2 is provided between every two adjacent multi-peak teeth A9. The intersection of the top surface of the multi-peak tooth B14 and its left end surface forms a straight cutting edge 15. A stepped surface B is provided between the top surface of the multi-peak tooth B14 and its front end surface, and between the top surface of the multi-peak tooth B14 and its rear end surface. The intersection of the stepped surface B and the left end surface of the multi-peak tooth B14 forms a stepped cutting edge B16. A plurality of third cutting edges 17 intersecting with the stepped cutting edge B16 are provided on the stepped surface B.

[0037] The distance between every two adjacent multi-peak teeth A9 on the saw blade body 1 is equal, and the distance between every two adjacent multi-peak teeth B14 on the saw blade body 1 is equal. Both the multi-peak tooth A9 and the multi-peak tooth B14 are cemented carbide teeth.

[0038] The working process of the present utility model is as follows:

[0039] S1. The worker fixedly installs the saw blade body 1 on the main shaft of the cutting equipment, and then fixes the metal part tooling to be cut. The cutting equipment is turned on. The cutting equipment drives the main shaft to rotate, the main shaft drives the saw blade body 1 to rotate, and the saw blade body 1 drives each multi-peak tooth A9 and each multi-peak tooth B14 thereon to move synchronously; then the cutting equipment controls the rotating saw blade to move towards the metal part.

[0040] S2. The first multi-peak tooth A9 cuts two sink grooves 19 on the metal part 7. As Figure 11 shown, then the straight cutting edge 15 of the first multi-peak tooth B14 cuts off the materials on both sides of the sink groove 19, thereby cutting an opening 8 on the metal part 7. As Figure 4As shown; subsequently, the two stepped blades A12 of the second multi-peak tooth A9 respectively perform preliminary cutting on the materials on both sides of the opening 8, and then the two stepped blades B16 of the second multi-peak tooth B14 continue to cut the materials on both sides of the opening 8, thereby expanding the width of the opening 8;

[0041] Among them, in step S2, when the four first tool tips 11 on the multi-peak tooth A9 perform cutting on the metal part 7, the cutting forces generated during the cutting process are respectively distributed to the four first tool tips 11, thereby ensuring that the four first tool tips 11 on the multi-peak tooth A9 will not be damaged, ensuring that the entire saw blade can be used for a long time. Compared with the saw blade Figures 1 to 3 as shown, it has the characteristic of longer service life.

[0042] In addition, the process of cutting the opening 8 on the metal part 7 is as follows: the four first tool tips 11 of the multi-peak tooth A9 cut two counterbores 19 on the metal part 7, and then the straight blade 15 of the multi-peak tooth B14 cuts off the materials on both sides of the counterbore 19, and finally realizes cutting the opening 8 on the metal part 7. It can be seen from this that the saw blade performs cutting in two times, and the cutting forces generated during the two cutting processes are not large, so as not to damage the four first tool tips 11, ensuring that the entire saw blade can be used for a long time. Compared with the saw blade Figures 1 to 3 as shown, it has the characteristic of longer service life.

[0043] S3. In this way, by alternately cutting the metal part with each multi-peak tooth A9 and each multi-peak tooth B14 on the saw blade, the metal part 7 can be finally cut off.

[0044] Among them, it can be seen from step S2 that when the stepped blade A12 of the multi-peak tooth A9 cuts the material on one side of the opening 8, since there are multiple second tool tips 13 on the stepped blade A12 itself, and the second tool tips 13 are very sharp, therefore, it is ensured that the stepped blade A12 cuts the material on one side of the opening 8 more smoothly, the resistance of the stepped blade A12 to the material is small, and further it is ensured that after the metal part 7 is cut off, there are no burrs at the fracture, thereby greatly improving the cutting quality of the metal part 7.

[0045] Similarly, when the stepped blade B16 of the multi-peak tooth B14 cuts the material on one side of the opening 8, since there are multiple third tool tips 17 on the stepped blade B16 itself, therefore, it is ensured that the stepped blade B16 cuts the material on one side of the opening 8 more smoothly, the resistance of the stepped blade B16 to the material is small, and further it is ensured that after the metal part 7 is cut off, there are no burrs at the fracture.
